So I bent some valves a few months back and I got another head for cheap and I sent it out to get cleaned up. It was slightly warped in one corner so had to be milled .010. What will my c/r be at with only two layers of the oem gasket?? Currently USDM H22a4 with 10:1. Also what kind of cheap porting can me and my trusty dremel do?? (Im going to build up the og head so I wanna play a little with this one)

 

the gasket will make the compression around 10.2, I'm not sure on the milling, but I would guess .2 points also. so around 10.4
